In afternoon trade, the S&P/ASX 200 Index (ASX: XJO) is on course to record a disappointing decline. At the time of writing, the benchmark index is down 1% to 8,162.7 points.

Four ASX shares that are falling more than most today are listed below. Here's why they are dropping:

Healthco Healthcare and Wellness REIT (ASX: HCW)

The Healthco Healthcare and Wellness share price is down almost 6% to 91 cents. This follows news that it has issued breach notices to Healthscope for failing to pay all rent due for March 2025. While the company notes that part payment of the rent has been received, it will enforce its legal rights and seek to replace Healthscope's tenancies with other hospital operators in the event the breaches are not remedied. In light of these breaches, the company has withdrawn its guidance for FY 2025.

Life360 Inc (ASX: 360)

The Life360 share price is down 6% to $22.01. This follows a pullback in the location technology company's shares on the NASDAQ index last night following a market selloff which impacted tech stocks more than most. This has seen the S&P/ASX All Technology Index fall 1.5% today. The team at Goldman Sachs is likely to see it as a buying opportunity. Earlier this week, the broker reaffirmed its buy rating with an improved price target of $27.00. This implies potential upside of 23% for investors over the next 12 months. It said: "We update our estimates to incorporate Life360's 4Q24 result. We reiterate our Buy rating and increase our price target to A$27 (from A$25). We increase our FY25-27E Ebitda forecasts by c.2%."

Mineral Resources Ltd (ASX: MIN)

The Mineral Resources share price is down almost 10% to $21.61. A number of shares with exposure to lithium are tumbling on Tuesday. This may be due to concerns that tariffs could impact electric vehicle sales and ultimately demand for lithium. This latest decline means that Mineral Resources' shares are now down a whopping 68% since this time last year.

Origin Energy Ltd (ASX: ORG)

The Origin Energy share price is down 5% to $10.41. This has been driven largely by the energy retailer's shares going ex-dividend this morning for its latest payout. Last month, Origin Energy released its half year results and declared a fully franked 30 cents per share interim dividend. This was up 9.1% on the prior corresponding period. Eligible shareholders can look forward to receiving this payout later this month on 28 March.
